Working Principle
- The module uses infrared sensing elements to detect reflected infrared light from a surface.
- Light-coloured surfaces generally reflect more infrared light than dark-coloured surfaces.
- Each sensing channel responds to the infrared reflection received from the surface below it.
- The individual channel outputs allow a microcontroller to determine which sensing positions are over a line.
- By processing multiple sensor signals, a robot can estimate line position and adjust its movement.
- Detection performance depends on surface material, sensor distance, lighting conditions, and calibration.
